Application filed .Tuly 29, 1912. Serial No. 711,987.

To all flo/tout it muy concern Be it known that I, (l1-mimics E. Lann, a citizen oi' the United States, residing at Sehastapol, in the county oit' nonoma and ttat-e of California, have invented new useful lmprovements in Foot-Rests Shoe-Clamps, ot which the 'following specilication.

This invention relates to a toot rest shoe clamp.

it is the object ot' this invention to provide a toot rest and shoe clamp t'or use on shoe-hlacking stands t'or securely holding the shoe against movement while it is being blackened and polished.

Another object is to provide a device of the above character which is simple in con struction and operation, and which is so constructed that the shoe may loe easily and quickly clamped thereon and released therefrom.

The invention resides in a shoe clamping means mounted on a suitable foot rest and means for operating the shoe clamp, by which it may he clamped and locked against ,shoes ot various widths, without necossitzit .ing adjustment.

The invention further consists ot the parts and the construction and combination ot' parts as hereinafter more 'fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a vertical section o't the invrnn tion, partly in elevation. lFig. 2 is a plan view with parts broken away.

ln the (Llrawings A represeiits the sole su pporting portion ot' the device which is preteraloly formed of cast metal. The sole snpport A. is in the 'torni of a plate, and iis designed to be mounted on a staiulard 2, of any suitable description. Downwardly project-ing flanges i?) areI 'formed on the outer edges oit the `sole support A, and extending on opposite sides oi the standard 2 are secured thereto by means oi. holts 4t. Formed integral with the sole support A is a heel rest 5, which consists of a horizontal pro- `jecting shelf or flange carried on a `transverse vertical wall ,6, extending between the flanges 3. Thelnpper end of the wall (5 terminates in a transverse rib or 'flange 7,which extends above the face oit the sole support n and is designed to engage a shoe at the point of juncture between the heel and sole thereof. The sole support A, flanges 3, wall (l,

and

is a

and

and I,

rib T, and the heel support 5 are preferably i cast to 'torni au integral striuzturc. Mount ed on the wall (i beneath the sole supporting plate a horizontally extending bracket t5 'termed with a horizontal longitudinally extending slot t). adjacent its outer end. This bracket tu may he lorined integral with the wall t3, or may be connected thereto by screw threads, as shown in liig. 1. 4ltlntending through the slot l) and slidable therein, in a pin 1() on which is mounted a levcr-arm 11, which arms is designed to be rocked in relation to the bracket 8 with the pin 10 as a ifnloruni. lVonnd on the bracket S and bearing between the wall ti and the leverarm 11, is a helical spring 12 which is tensioned to bear between the wall and the lever-arm l1 in such manner as to normally retain the latter in its outermost position in relation to tho bracket 8; the pin 10 hearing against the outer end ot the slot l) lo limit the outward movement ol the leverarm 1 1. ["orlncd on the upper ond olf the lever-ar1n 11. is an eccentric cam taco 13, which is designed to bear against the spring 12 when the leverarm 11 is rocked in an npward direction as will presently loe dcscribed.

livotally mounted on the upper tace ot the solo snppr'n-ting plate A on a pivot pin 11i is a pair ot solo clamping arms 1 5, which arms are `formed at their outer ends with upwardlyr and inwardly extending hookshaped portions 16, which are adapted to engage the outer edges ot the shoe soles. The sole clamps 15 arc intended to be rocked on their pivot pin lil so as to throw the members 1li in and ont o't` engagement with the shoe by 1n aus o'l the levenarm 11, which is connected to the clamps 15 by means ot' links 17 pivotally connected at one end to the lever-arm 11, and pivotally connected l at the other end to downwardly projecting i swivels 18 carried by the clamps 15; the swivels 18 extending through pertorations or slots 19, formed in the sole supporting plate A. and serving to permit a necessary oscillating movement o t the clamps in relation to the links. The clamps 15 are normally retained in their outermost position by reason of the spring 12 bearing against the upper portion of the lever-arm 11; the i pressure ot' the spring 12 tending to rock the lower portion of the lever-arm 11 in an inward direction,

which movement is trans- 1 mitted through the links 17 to rock the clamps in an outward direction on the pivot pin 14.

In the operation of the invention the shoe is placed with the sole resting on the plate A and the heel resting on the shelf or flange 5, and engaged on its inner edge by the wall 6 and at its point of juncture with the sole by the rib 7 g the upwardly projecting portions 16 on the clamps 15 extending upwardly on opposite sides of the shoe sole.

The lever-arm 11 is then rocked in an upward direction on the pivot pin 10, into the position indicated in dotted lines in Fig. 1,V ther-eby causing the clamps 15 to move inwardly by means of the links 17 and drawing' the members 16 into engagement with the sole of the shoe. In this operation, the pivotal connection between the links 17 and l the lever-arm 11 moves from its normal position below the pivot pin 10 to a point thereabove, so that the spring 12 bearing` against the cam face 13 on the upper end of the lever-arm 11 will act to lock the latter in its uppermost position.

It is to be observed that when no opposition is made to the inward movement of the clamps 15, that the lever-arm 11 will swing freely on the pivot 10 from its lowermost to its uppermost position without an appreciable compression of the spring 12; however, when the outer ends of the clamps close against the edges of a shoe sole tol limit their inward movement, the pivot pin 10 of the lever 11 will move inwardly along' t the slot 9 in oppositionto and compressing t the spring 12. The slot 9 thus serves as a means for allowing the fuflcrum point or pivot pin 10 of the lever 11 to shift any distance that may be required on the blocking of the clamps 15 to allow the links 17 being swung to their locking position above the pin 10. By this construction the clamps 15 are adapted to engage shoe soles of various widths without necessitating any adjustment of the lever 11 other than the automatic shifting of its fulcrum.

From the foregoing it will be seen that when it is desired to clamp a shoe to the sole support A, it is only necessary to rock l the lever 11 from its lowermost to its upperf most position, and that when it is desired j to release the shoe, the lever 11 will be'rocked j from its uppermost to its lowermost position; the spring 12 acting to normally retain r the lever in either position.

Having thus described my invention, what I claim and desire to secure by Letters Patl ent, 'isl. In a foot rest and shoe clamp, the coml bination of a shoe supporting membeiga sole engaging clamp thereon, a hand-lever, and means including a resilient spring coperating with said lever for operating the clamp by the lever whereby the clamp can be closed and lockedv against shoe soles of various widths. l

2. In a foot rest and shoe clamp, the combination of a shoe supporting member, a sole engaging cla-mp thereon, consisting of a pair of cooperating jaw-members pivotedA on the shoe support, a link connected to each of the jaw-members, a lever to which the links are connected, and means including a sliding pivot for said lever for locking'` the leve-r in either of two positions to retain the clamp in or outl of engagement with a shoe. f

3. In a foot rest and shoe clamp, the combination of a shoesupporting member, a sole engaging' clamp thereon, consisting of a pair of coperating jaw-members pivoted on the shoe support, a link connected to each of the jaw-members, a lever to which the links are connected, means including a shifting fulcrum for said lever for locking the lever inv either of two positions to retain the clamp in or out` of engagement with a shoe, and resilient means wherebythe clamp can be closed and locked against shoe-soles of various widths by the operation of the lever.

4. In a foot rest and shoe clamp, the combination with. a shoe supporting member, of a pair of cooperating jaw-members pivoted on the shoe support, a swivel carried by each jaw-member, a linkattached to eachswivel, a lever-arm to which the links are connected, said lever-arm having a shiftable fulcrum, and means for locking the lever-arm in either of two positions to retain the jawmembers in or out of engagementV with aV shoe.

5. In a foot rest and shoe clamp, the combination with a shoe supporting member, of a pair of cooperating jaw-members pivoted on the shoe support, a swivel carried by each j avv-member, a link attached to each swivel, a lever-arm to which the links are connected, a bracket formed with a slot, a pin extending' through said slot and movable lengthwise thereof, on which the lever-arm is fulcrumed, and a Vspring bearing. against the lever-arm adjacent the pin to normally retain the lever-arm in either of two positions.
